Abstract (en)
The element (3``) has plane windings (31-36) formed in a N number of lower conductive levels i.e. metallic levels, of an integrated circuit with respect to specific number of windings, where the windings (32, 33) are interdigitized in a same conducting level and are of rectangular, circular or orthogonal shape. Outer ends (311, 321) define access terminals that are placed at the exterior of the windings (31, 32), which are formed in respective levels. The windings are connected with respect to one another by a number of vias (51-55) that is equal to a number of conducting levels.
Abstract (fr)
L'invention concerne un élément inductif (3") formé d'enroulements plans (31, 32, 33, 34, 35, 36) dans différents niveaux conducteurs, les enroulements étant réalisés dans un nombre de niveaux inférieurs d'une unité par rapport au nombre d'enroulements, deux (32, 33) des enroulements étant inter-digités dans un même niveau.
